Venohemodynamics after superficial vein and calf perforating vein surgery

Objective To assess the role of superficial vein and calf perforating vein in chronic venous insufficiency of lower limbs. Methods Consecutive seventy-five cases (78 limbs) of slight PDVI ( I° -Ⅱ°) were evaluated. Venous hemodynamics were detected by color duplex, color Doppler velocity profile technology and APG preoperatively, in the first month, the third month and the first year postoperatively. Data were statistically analyzed. Results Symptoms and signs disappeared in 88. 5% (69/78) limbs. The ulcer-healing rate was 92. 8% ( 13/14). The postoperative VFI at each check-point significantly decreased than that before operation (P0.01 ). The VFI, RVF significantly improved in Group SEPS(P0.01). But the postoperative venous reflux volume and EF were not significantly changed than that before operation (P0.01). Conclusions Superficial venous reflux can be effectively broken up by the operations. Venous stasis on calf effectively decreased by subfascial endoscopic perforator surgery (SEPS). But neither of the two procedures greatly improve the hemodynamic status of deep vein.
